nally extendingribs 19 for supporting the box out of contact with thesurfacev upon which the box rests.

The notches for the strips 7 are in the're inforcing strips 16, and itwill be noted from an inspection of Fig. 2 that the notches do not cutthrough the strips.

The improved stove is especially designed for use with press boxes, andthe box or container of the stove is introduced directly into the box.The current is supplied to the resistance coils by way` of the wires 12and 15 and assing through the said coils they lbecome liighly heated andwill heat the press The current passes by way of the wire 13 and wire 14to the outermost coils 8. Hence the current passes by Way of the endcoils 9 and 9a'to the adjacent coils, and by way of the coils 10 and 10Bto the innermost coils. From the innermost coils the current passes byway of the wires 11 and 12 to the source. The current is divided as itleaves the wire l5, passin in both directions and is again united at tA1e wire 12. It will be evident that instead of Wiring the coils inparallel, or dividing the current as above mentioned, the current may besupplied at one end and may pass out at the other, this being a matterof convenience. The strips 7 are braces for the insulating plates 4.
